How to make while loops countdown seconds in javascript?

Here's an example of how to create a countdown in seconds using a while loop in JavaScript:

var count = 10;

while (count > 0) {
    console.log(count + " seconds remaining");
    // wait for 1 second
    setTimeout(function () {}, 1000);

console.log("Countdown complete");

In this example, the count variable is initialized to 10 and the while loop continues as long as count is greater than 0. Inside the loop, the current value of count is displayed, count is decremented by 1, and the setTimeout function is used to pause the loop for 1 second (1000 milliseconds).

After the while loop finishes, a message indicating that the countdown is complete is displayed. Note that this code will only work correctly if run in an environment that supports setTimeout (such as a browser JavaScript console).
